Chayote, Water Chestnut and Grass Carp Tail Soup

Why people make this soup

When you or a child has been sick for a while, or has just come through surgery, the gut often feels sluggish and appetite is the first thing to disappear. This simple, clear soup is a go-to in Cantonese home cooking for exactly that moment: it is light enough for a sensitive stomach yet nourishing enough to help the body start rebuilding. The chayote brings a clean sweetness and broad nutritional value, while the water chestnuts add a gentle cooling quality to clear any leftover heat or phlegm — something that often lingers after a cold or chest infection.
